Four indium-based heterometallic metal-organic frameworks In3M(IMDC)3(NO3)2(H2O)6*solvent (2-M, M = Mn, Co, Zn, Mg, H3IMDC = imidazole-4,5-dicarboxylic acid) have been made under solvothermal conditions, and characterized by single-crystal X-ray diffractions, energydispersive X-ray spectroscopy, infrared spectroscopy, thermogravimetric analysis and powder X-ray diffractions. Structural analysis indicates that 2-M exhibit 3-dimensional porous frameworks generated by linking three intersected 1-dimensional In-IMDC helical chains with different M2+ ions, respectively. Powder X-ray diffractions reveal that 2-M exhibit good thermal and water stability. What's more, 2-M show moderate gas adsorption abilities that can be modulated by introducing different M2+ ions. Finally, the solid-state luminescent emissions of 2-M are also elucidated at room temperature.
